Phosphoric acid
phosphoric acid for agriculture Introduction:
Belong to strong acid, phosphate crystallization point (freezing point) for 21 ºC, precipitation when temperature below the half water (ice) chip.Usually phosphate in above 10 ºC or more, of course, also not knot under low temperature (ice) crystal, this is due to the nature of phosphate is too cold, also is the actual listing of phosphate in 21 ºC will deviate from its junction (ice) crystal point, not immediately (ice) crystal phenomenon exists.But at such a low temperature for a period of time, phosphoric acid can easily form crystals in its resting state.
Phosphoric acid crystals, like other liquid crystals, are physical rather than chemical changes.The chemical properties will not be changed by crystallization, that is, the quality of phosphoric acid will not be affected by crystallization, as long as the temperature melting or heating water dilution solution, still can be used normally.
